Background and Purpose

The the specific objectives for this website are to provide the following:

An on-going BLOG of observations and seasonal events that relate to tree fruit diseases and their control in the mid-Hudson Valley based on observations from orchards at the Hudson Valley Lab in Highland, NY or from nearby commercial orchardsNOTE: Those wishing to receive e-mail alerts when I post updates on the blog-page should enter their e-mail addresses and hit the “subscribe” button shown on the right side of this page. You can unsubscribe just as easily if the posts prove bothersome.

An organized collection of relevant extension publications and photographs from my archives that may be useful to fruit growers and other extension professionals interested in management of tree fruit diseases. (go).

An archive of plant pathology field research reports (go) and weather data (go) from the Hudson Valley Lab that covers the period from 1974 to 2013.

Extension information on apple diseases is being organized under the “Apple Diseases” page of this website with the objective of providing background information on the most common diseases and disease-related problems confronted by apple growers in New York State. Links to relevant publications show the date that the articles were written or last revised, so readers should be aware that some information may be outdated, especially where articles refer to specific chemical control strategies. Always read current product labels before applying any agrichemical products. Many current product labels can be accessed quickly via the CDMS website (go), and products labeled for use in New York State can be accessed at the NYSPAD website (go).

This web-site is is part of my retirement bucket list and therefore will never be “complete.” Thus, some of the subject matter areas listed in menus may lack content.

Acknowledgements: Funding to create this website was provided via an internal competitive grant for Hatch and Smith-Lever dollars provided to Cornell Cooperative Extension and the N.Y. State Agricultural Research Station at Geneva by USDA/NIFA. Appreciation is expressed to Jane Kostina who provided the initial design for the website and uploaded many documents.
